Details

For a crossover point C = -b2/b3 of the two simple regression lines, Widaman et al. (2012) proposed to estimate C
using the non-linear regression of the form y = A0 + A1*(x1-C) + A2*(x1-C)*x2. The function nonLinearC() estimates
C using the non-linear regression and calculates the confidence intervals for C based on the standard error of C
obtained from a non-linear regression.

Value

C_Hat

estimate of C from a non-linear regression

SE

standard error of C from a non-linear regression

LowCI

lower bound of confidence intervals for C based on a non-linear regression

UpperCI

upper bound of confidence intervals for C based on a non-linear regression
